Some of the most common suggestions I've seen are to remove energy altogether, and make the jade sphere mobile.
I however think it's worth considering to instead remove cooldown on jade sphere, and instead let the player redeploy the jade sphere at any moment and any other place they want, as long as they're capable of paying the energy cost.
This kind of solves the problem of jade sphere being immobile, as it can just be resummoned at a desired location, but the player is forced to build up the required energy beforehand.
